I'm using

title Xen
kernel (hd0,4)/boot/xen.gz dom0_mem=131072 com1=115200 noht noreboot
module (hd0,4)/boot/vmlinuz-2.4.26-xen0 root=/dev/sda5 ro


title linux-smp
kernel (hd0,4)/boot/vmlinuz-smp root=/dev/sda5 devfs=mount acpi=ht 
resume=/dev/sda1 max_loop=128
initrd (hd0,4)/boot/initrd-smp.img

The Xen command line is exactly what was working two days ago, except that 
(hd0,4) was (hd0,0) and /dev/sda5 was /dev/sda1.  (This was cut & pasted from 
my notes, so the chance of a typo in, say, com1 is reduced -- not eliminated, 
of course.  At this point I'm looking for 1/l O/0 sillies that could have 
crept in, but haven't found anything yet.)

the linux-smp works fine, of course.

Good to know.
